Selecting an entry through horizontal tabs

I have a compiled a custom dictionary with Dictionary App Builder and I have been trying to select words through the horizontal tabs, but for some reason selecting entries this way is not working. I have tried making different test dictionaries and still I have not been able to solve the problem.
Is there a particular setting I have to use in order to solve this?

Can you make your app available for me to test it?

What is your source in LIFT or XHTML? What generated it?


Thank you very much for your response. I have noticed that all the entries in the App are capitalized, so I changed them to small caps and now everything is OK.

Great thanks for the update with good news.
